Dental Intrusion in Primary Dentition: Clinical Management Protocol

Dental intrusion is one of the most severe types of dental trauma in childhood. It occurs when a tooth is forced into the alveolar bone, partially or completely disappearing from view. This injury is more common in primary dentition due to the elasticity of bone and periodontal tissues in young children.

✅ What Is Dental Intrusion?
Dental intrusion is defined as the axial displacement of a tooth into the alveolar bone, caused by traumatic impact. It is frequently associated with falls during early childhood.

Key features include:
▪️ Tooth appears shortened or missing
▪️ Gingival bleeding
▪️ Pain or discomfort
▪️ Possible damage to surrounding tissues

📌 Recommended Article :

PDF🔽 Guidelines for the management of traumatic dental injuries in the primary dentition ... The lesions can compromise dental tissue (enamel, dentin, root), dental pulp, alveolar bone, and periodontal ligaments. Soft tissues such as lips and cheeks are also included.

✅ Dental Intrusion in Primary vs. Permanent Teeth
Management differs significantly depending on whether the intruded tooth is primary or permanent.

➤ Primary Teeth
▪️ The main goal is to protect the permanent tooth germ
▪️ Many intruded primary teeth re-erupt spontaneously
▪️ Active repositioning is usually not recommended
▪️ Extraction may be indicated in selected cases

➤ Permanent Teeth
▪️ Treatment aims to preserve pulp vitality and periodontal healing
▪️ Repositioning (spontaneous, orthodontic, or surgical) may be required
▪️ Higher risk of pulp necrosis and root resorption

Before and After Tooth Extraction: Dental Care Guidelines to Promote Safe Healing

Tooth extraction is a common dental procedure, but proper care before and after the extraction is essential to prevent complications such as bleeding, infection, or dry socket. Understanding why each instruction matters helps patients actively protect the healing area and recover safely.

📌 Recommended Article :

Dental Article 🔽 How to Prevent Dry Socket After Tooth Extraction: Signs, Prevention, and Treatment Guide ... Preventing dry socket is a key responsibility shared by both dental professionals and patients, involving proper surgical technique, patient education, and targeted pharmacological management.

This guide explains, in simple and clear language, what to do before and after a dental extraction, and the scientific reasons behind each recommendation.

Advertisement

✅ Pre-Extraction Instructions and Their Importance

1. Inform the dentist about medical conditions and medications
Patients should report systemic diseases, allergies, and all medications they are taking.
Why this matters:
Certain conditions (such as bleeding disorders, diabetes, or heart disease) and medications (anticoagulants, antiplatelets) can increase the risk of excessive bleeding or delayed healing.

2. Eat a light meal (unless instructed otherwise)
For routine extractions under local anesthesia, a light meal is recommended.
Why this matters:
It helps prevent dizziness or fainting caused by low blood sugar after the procedure.

3. Maintain good oral hygiene before the appointment
Brushing and gentle flossing should be done before the extraction.
Why this matters:
Reducing oral bacteria lowers the risk of postoperative infection.

📌 Recommended Article :

Dental Article 🔽 Bleeding After a Tooth Extraction: How to Stop It Safely ...Bleeding after a dental extraction is common and usually normal, especially during the first hours. However, knowing what is normal, how to control bleeding, and when to seek help is essential for proper healing.

✅ Post-Extraction Instructions and Why They Are Essential

1. Avoid physical effort
Patients should avoid exercise, lifting heavy objects, or intense physical activity for at least 24–48 hours.
Why this matters:
Physical exertion increases blood pressure, which can dislodge the blood clot and cause bleeding.

2. Do not rinse or spit forcefully
Mouth rinsing, spitting, or using straws should be avoided during the first 24 hours.
Why this matters:
These actions create negative pressure that may remove the blood clot, leading to delayed healing or dry socket.

3. Avoid heat sources
Patients should not expose themselves to hot environments, saunas, or direct sunlight.
Why this matters:
Heat causes blood vessel dilation, increasing the risk of postoperative bleeding.

4. Sleep slightly elevated
Sleeping with two pillows or in a semi-upright position is recommended.
Why this matters:
Elevation reduces blood flow to the surgical area, helping control swelling and bleeding.

5. Do not touch the wound with the tongue or fingers
The extraction site should not be manipulated.
Why this matters:
Touching the wound can introduce bacteria and disturb the clot, increasing infection risk.

6. Avoid smoking and alcohol
Smoking and alcohol consumption should be avoided for at least 72 hours.
Why this matters:
Smoking reduces oxygen supply to tissues, while alcohol interferes with clot stability, both of which delay healing.

7. Consume soft foods and avoid spicy or seasoned meals
During the first 24–72 hours after tooth extraction, patients should consume soft, cool, and non-seasoned foods, such as yogurt, mashed potatoes, soups at room temperature, and smoothies (without straws). Spicy foods, chili peppers, acidic, and heavily seasoned meals should be avoided.
Why this matters:
Hard or crunchy foods may traumatize the extraction site, while spicy or highly seasoned foods can irritate the surgical area, increase inflammation, and cause discomfort. Additionally, heat and strong condiments may interfere with blood clot stability, increasing the risk of delayed healing or postoperative bleeding.

Blandin–Nuhn Mucocele: Etiology, Clinical Features, and Effective Management

A Blandin–Nuhn mucocele is a benign, mucus-filled lesion arising from the anterior ventral glands of the tongue, known as the glands of Blandin–Nuhn.

📌 Recommended Article :

PDF 🔽 Epstein's pearls and Bohn's nodules: definition, characteristics and case report ... Bohn's nodules and Epstein's pearls are benign cysts found in the oral cavity of a newborn. They are observed as small lumps that are distributed in the oral cavity and disappear over time.

These lesions represent a subtype of oral mucoceles and are caused by extravasation of mucus following trauma or ductal disruption. They are more frequently observed in children and young adults, although they may occur at any age.

Advertisement

✅ Etiology
The primary etiological factor is mechanical trauma to the ventral surface of the tongue, which leads to rupture of the minor salivary gland ducts. Common contributing factors include:

▪️ Chronic tongue biting
▪️ Sharp incisal edges or orthodontic appliances
▪️ Accidental trauma
▪️ Parafunctional habits
Unlike retention cysts, Blandin–Nuhn mucoceles are classified as mucus extravasation phenomena, lacking an epithelial lining.

📌 Recommended Article :

▪️ Conventional surgical excision (gold standard)
▪️ Laser excision (CO₂ or diode lasers)
▪️ Cryosurgery (less commonly used)

Key surgical principles include:
▪️ Adequate depth of excision
▪️ Removal of adjacent glandular tissue
▪️ Careful hemostasis due to tongue vascularity
Recurrence is uncommon when the lesion and associated glands are completely removed.

📊 Comparative Table: Differential Diagnosis of Ventral Tongue Lesions

Lesion	Key Clinical Features	Diagnostic Considerations
Blandin–Nuhn mucocele	Soft, fluctuant ventral tongue lesion	History of trauma; extravasation phenomenon
Hemangioma	Bluish-red lesion, blanching on pressure	Positive diascopy; vascular origin
Pyogenic granuloma	Rapidly growing, ulcerated mass	Inflammatory response to irritation
Salivary gland neoplasm	Firm, persistent mass	Requires biopsy to rule out malignancy

💬 Discussion
Blandin–Nuhn mucoceles are often underdiagnosed due to their unusual ventral tongue location and resemblance to vascular lesions. Misdiagnosis may lead to inappropriate management, such as aspiration or incomplete excision, resulting in recurrence. Awareness of this entity is essential for accurate diagnosis and effective treatment, particularly in pediatric dentistry and oral medicine.

✅ Why Does Bleeding Occur After a Tooth Extraction?
When a tooth is removed, a small wound remains in the bone and gum. The body responds by forming a blood clot, which acts as a natural “bandage.”

This blood clot is essential for healing.
If it does not form properly or is disturbed, bleeding may continue longer than expected.

Common reasons for prolonged bleeding include:
▪️ Rinsing or spitting too soon
▪️ Touching the area with the tongue or fingers
▪️ Physical effort too early
▪️ Smoking or vaping
▪️ Certain medical conditions or medications
